April 20 [Day 61] (Valley View site) The temperature of 20C between 1600 and 1700 equaled the season’s high, rising from 3C and remaining at 17C at 1900. Ground winds were variable and generally light, ridge winds were SE light to moderate and cloud cover was 0% to 1330 after which it was 30-50% cumulus providing good viewing conditions. Once again raptor movement was thin with only 10 birds moving between 1040 and 1729, and even resident birds were hard to find. The flight comprised 1 Osprey, 2 Sharp-shinned Hawks (1a,1u), 2 Cooper’s Hawks (1a,1u), 2 Northern Goshawks (1a,1j), 1 Red-tailed Hawk and 2 Golden Eagles (1j,1u). The only new season record was 4 Pine Siskins [#59] flying by at 1405, while 21 Tundra Swans flying east at 1119 was the latest record ever at the site. 12.25 (709) OSPR 1 (2), SSHA 2 (34), COHA 2 (6), NOGO 2 (79), RTHA 1 (82), GOEA 2 (2068) TOTAL 10 (2717)
